Sechelt: SCRAS presents Paul Gray

January 11 @ 7:30 pm - 9:00 pm

By Donation

The Sunshine Coast Royal Astronomical Society presents Paul Gray, the editor of the RASC Calendar, who will be doing a presentation on Dark Nebulae, at the Sunshine Coast Art Centre in Sechelt. A dark nebula or absorption nebula is an interstellar cloud so dense that it obscures the light from objects behind it, such as background stars & emission or reflection nebulae. Interstellar dust grains, coasted with frozen carbon monoxide & nitrogen, in the coldest, densest parts of larger clouds effectively block the passage of light at visible wavelengths. These clouds are the spawning grounds of stars & planets, and understanding their development is essential to understanding star formation.

The largest dark nebulae, like the Coalsack Nebula & the Great Rift, are visible to the naked eye, appearing as dark patches against the brighter background of the Milky Way.

It starts at 7:30pm, admission is by donation at the door, and everyone’s welcome. http://www.coastastronomy.ca/
